Diagnosis Of Battery Voltage
General Description
A signal below the threshold is not plausible, since the processor of the ECU is not operational if the voltage is less than or equal to 2.5V. A substitute
value is therefore used.
The max. value check is only effective after a delay period from the end -of-start and only with a vehicle speed greater than zero (with a speed signal
without faults).
The check of the min. value (fault in the vehicle's electrical power supply system) is only allowed after a delay time from the end-of-start, when the
voltage has recovered from the starter activation.
